Not bad,not great either. Can't say if it's an improvement over the Cooler Master,they seem pretty equal in performance and build quality. Biggest difference might be the primary cap which afaik with Cooler Master comes from Teapo (@85C) and with EVGA from Nippon Chemicon (@105C,which is better anyway),but the rest of the caps seem pretty equal.
Saw the next where Jon from ones jonnyguru,now Corsair,says that the fan is probably the first to go.

Looking at the fans specs as the Cooler master the better fan with a life expectancy of 160.000 hours where the EVGA fan seems to have one of 80.000 hours.The last one is at 40C,the first i'm not sure of so might be 25C as well.
The EVGA is btw not gold,but bronze efficiency rated. Well some and maybe too much info,but there you go.
